You are correct. The current version of firmware/software puts the laptop in Standby. However, the current drain is very low if the battery is nearly/fully charged. We've been doing this with Mac minis for quite some time with no apparent battery drain issues. We are, however, working on a scheme for Hibernation which may be an even lower power drain.

If you do feel like making us a connector.....

also, the bios doesn't support wake from USB
so pretty much, this post is just to show you the connector since thunder already said this

when i get the 2140 in the mail, ill try it out tho and see how the "into standby" works and goes on my battery

I'd love to, but my chances of getting these connectors from Dell is, well,....not good

The "into Standby" will work fine since it uses the Microsoft .NET framework commands, which are running when you run the PSUmoni application. However, if your bios doesn't support wake from USB then you may be forced to use the hardware ACPI interface (ie soldering wires to your power switch), which is what we'd like to avoid. Is there any chance that a BIOS update would add this capability?

Well you could have some manufactured, unless that's stepping on someones patent leather shoes.

Specialty Connector Manufacturer

Actually just updated the bios and it still doesn't look like it is an option
are there a lot of comps that have that option? i thought it was just macs...?

These are great computers for carputer, so getting an adapter to work from the p2140 and being able to sell it through mp3car would be a great idea as far as marketing the p2140. They can be had for about $250.00 on ebay and sport a ton of good features. Laptop hard drive, power cpu, slim type dvd drive, external power supply, dual big fans (great for in car).
Really though soldering the power button may be the only option. Unless you can make it work with the wake on lan. Going in to standby shoudlnt be to bad as long as you are using a second battery and a battery isolator. This would allow you to use the USB shutdown and startup option efficiently.

That's a great price!

Unfortunately, if the power plug is a special size/shape I would have to have a plastic mold made for only a few hundred parts. My guess is the math doesn't work...

I do actually have a wake-on-link solution designed, built, and tested, but it requires that the laptop support wake-on-link. Apparently this is not all that common.

Solder the leads you’ve just cut to the ends of that like this:
Red (12vin CPU) to Red (12vout PSU)
Brown (12vin CPU) to Red (12vout PSU)
Black (Ground CPU) to Black (Ground PSU)
White (Ground CPU)to Black (Ground PSU)
Also, solder the screen (Wire Mesh Ground) to black.
Fold the Green and Yellow wires back against the cable and tape them up.
Tape each join up individually, then tape the whole lot together.

what do the green and yellow wires go to?

Well I just won a Optiplex SX260 on ebay for $160 (DVD, 512MB, 30GB, P4 2.8GHz) so I'll be using this guide once it arrives. I already have a P1290 do you think that will power it ?? I know someone running one in their car and he says it's running off a 12v 6.5A supply

The P2140 is definitely a better solution. Maybe I can sell the P1290 and get some of the cost towards a P2140.
